-matic Brake for Engines, Pumps, and the Like; and I do hereby declare the following' to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in automatic stops ada ted for use in connection with-electricallydr1ven umps, engines, and other devices that reate to the same art.

This device is to be attached at any suitable location upon the apparatus upon which the said device is to be used; but,-as shown in the accompanying drawings and described hereinafter in the following specification, the said automatic stop is ada ted for use in connection with eleotricallyriven devices, en-

gines, and other devices to which it may be easily adapted for the purpose set forth.

The invention comprises novel means which may be connected practically to the reciprocating rod of a pum driven byany suitable motive power and a so having novel means which may fall in the path of an electric switch or means for starting and stopping the motive power which is used in connection therewith.

The invention is a sure stop for the above set forth" devices, and it is also comparatively simple in construction and inexpensive tomanufacture.

. The invention comprises, further, the vari-' ous objects, advantages, and combination of elements, which will be hereinafter more fully described and set forth and then referred to showing the same attached to a pump.

by the appended claims.

. For a full understanding of the details of construction, merits, advantages, and combination of elements reference is to be had to the following description and the accompanying drawings in connection therewith, wherein Figure 1 is an'elevation of the inventivon,

2 is anenlarged detail perspective view of the automatic stop. Fig. 3 is an elevation (of the invention as a plied to an engine. Fig] 4 is a detail view ofthe ratchet and friction-disk. r

Making renewed reference to the drawings,

ble graduations.

wherein the corresponding parts throughout the .several illustrations are designated by characters, 1 indicates the reciprocating rod of an ordinary pump, which is provided with a pitman 2, one end of which is provided with a slot 3, the outer end thereof being opened and the side walls of said slot being curved, the said slotted end of the pitman being adjustably connected to the operating-lever 4, which is pivotally mounted upon a stubshaft 5, which is journaled in suitable bearings in a vertical portion 6 of the frame of the apparatus. Also mounted upon the stubshaft is a friction-disk 7, which is adapted to have a friction-shoe 8 to engage therewith, which is'a part of the lever 4, this lever 4 being formed in two parts 9 and 10, the part 9 being mounted on the stub-shaft 5 and the part 10 is pivotally connected to the part 9. The said friction-shoeis made integral with the part 10 and is ada ted to engage the friction-disk, as clearly il ustrated in the accompanying drawings. The part 9 is provided with a ug 11, which is adapted to cooperate with the part 10 of the lever 4 to limit the movement thereof when the same is in operation. Pivotally mounted just below the journal of the said disk is a weighted brake 12, which is adapted to engage the periphery of said disk to prevent the retrograde motion of the same. To obtain a greater weighted levera e, the said lever is provided with a movab e weight 13, having an arched portion which is provided with a knife-edge for the urpose of en agement with notches 14, fbrmed in the ever 12, .for the purpose of.

holding the weight in the position desired.

Projecting from the fiat surface of the disk is a laterally-projecting pin 15, which as the disk rotates will engage one ofthe teeth of the ratchet 16, which is mounted upon a shaft 17, which is j ournaled in suitable hearing; in the frame of the apparatus.

xtending laterally from the vertical portion 6 is a horizontal portion 18, having a downwardlyrojecting portion 19 at the end thereof, whic ortion forms one of the bears-for the sha 17 A guide-plate 20 is proed, which extends parallel to the portion 18, the said plate being bolted or otherwise secured, as at 21, to the vertical portion 6, the said plate also being provided with suit- This late is adaptedto co- 0 erate with a weighted hammer 22, one end 0 which is screw-threaded into a movable head 23, the bore of which is threaded to engage threads 24 of the shaft 17. The graduations are for the ur ose of determining the horizontal travel of the weight-hammer. When the said weighted hammer has reached the end of the guide-plate 20 by the movement of the ratchet 16, which is rotated by the shaft 17, it Will fall tric switch 25 or in the vice used for starting powers.

The lever 4 is provided with a suitable guide 26, having a suitable catch device 27, which when the part 10 of the lever 4 is disconnected from the itman 2 and said part 10 resting in the catcffdevice 27 will cause the said automatic stop to be put out of action.

The operation of the form shown in Fig. 3 is as follows: The weighted hammer 22 upon reaching the end of the uidelate 20' will fall in the path of the hanfle a o the valve a, thus closing the said valve, thereby preventing the steamfrom entering the steam-chest, which will sto the engine.

From the f regoing it will be clearly observed that a very efficient and inexpensive device is provided whereby pumps which are driven by any suitable 'motive power ma be automatically stopped at a predetermlned moment.

Havin thus fully what is cfaimed as new is 1. A device of the class described, comprising a frame, a disk mounted therein, a lever to cooperate therewith, a brake to prevent the retrograde movement of said disk,.a shaft mounted within the frame, a ratchet thereon, means carried by the disk for rotating the ratchet and a hammer movably carried by said shaft.

2. A device of the class described comprising a frame, a disk mounted therein, a lever to cooperate therewith, means carried by the lever or turning the disk, a brake'therefor to revent the retrograde movement, a guideame for the said lever, a shaft mounted within the frame, a ratchet thereon, means carried by the disk for rotating the ratchet and the shaft therewith, a hammer movably carried by said shaft and a guide therefor.

3. A device of the class described comprising a frame, a disk mounted therein, a lever to cooperate therewith, a brake to prevent in the path of an elecpath of any other deand stopping motive described the invention,

the retrograde movement of said disk, a shaft mounted within the frame, a ratchet thereon, a pin carried by the disk for rotating the ratchet and a hammer to be actuated by the rotary movement of said shaft.

4. An automatic stop comprising a frame, a shaft mounted therein, a hammer movably carried by the shafts, means to guide the hammer in 1ts longitudinal movement of the frame and means to rotate the shaft.

5. An automatic stop comprising a frame, a shaft journaled therein, a ratchet thereon, means for rotating the ratchet and shaft and a hammer movably carried by the shaft.

6. An automatic stop comprising a frame, a shaft journaled therein, a ratchet thereon, means for rotating the ratchet and shaft, means for preventmg the retrograde movement of the first-named means and a hammer movably carried by the'shaft. 7. An automatic stop comprising a frame, a shaft journaled therein, a ratchet thereon, a disk carried by the frame and having means for rotating the ratchet, a lever having means for impartmg an intermittent movement to the shaft.

8. An automatic stop comprising a frame, a shaft journaled thereln, a hammer movably carried thereon, a disk and havin means to engage means carried by the sha t to rotate the said shaft and cause the said hammer to move longitudinally of the frame, and a lever having means to impart an intermittent movement to the disk.

9. An automatic stop comprising a frame, adisk having a lateral projecting pin and carried by the frame, a lever having means to im art a rotary intermittent motion to the disl z, a catch device for the lever, means to prevent theretrogression of the disk, a shaft I j ournaled in the frame, means carried by the shaft to be engaged by the said pin and a hammer movably carried by the shaft.
